GlassWire vs OpenSSH for Windows

GlassWire is a network monitoring and personal firewall application for Windows and Android that visualizes current and past network activity to help users spot malware, bandwidth hogs, and unfamiliar devices on their network. Its firewall includes an ask-to-connect mode that lets users approve or deny individual apps' network access, alongside a network time machine for reviewing historical connections. GlassWire also tracks data usage across devices and can alert users before they exceed set data limits, while its network scanner flags new or unknown devices joining a WiFi network. Over 53 million downloads have been recorded for the Windows and Android apps combined.

OpenSSH for Windows brings the widely trusted OpenSSH suite to native Windows environments, providing both client and server capabilities without requiring third‑party tools. It integrates with Windows authentication mechanisms and supports key‑based, password, and GSSAPI authentication. The package is maintained by Microsoft and the OpenSSH community, offering regular updates, compliance with FIPS standards, and compatibility with existing Windows security policies. It is ideal for administrators and developers who need secure remote access and automated file transfers on Windows servers and workstations.
